SCHURTER has launched a new series of highly compact filters with the introduction of the 5121 appliance inlet filter. The filter features an IEC C14 inlet that is surrounded by a closed metal housing, effectively shielding the mains input from interference. The new filter series is available in both standard and medical technology versions, with a rated current of up to 10 A / 15 A and wire connections.

The mains input is often a critical point of vulnerability in the housing, as interference can enter or exit the housing through the power cables or opening. The 5121 appliance inlet filter series provides a highly compact solution for preventing such interference. With this filter, users can effectively protect their equipment from both interference radiated through the opening and interference via power cables.

Applications

The new filter family is especially suitable for applications with very small installation depths that require high-frequency filtering of the mains input at the same time. The 5121 appliance inlet filter reliably shields high-frequency interference conducted through cables or radiated thanks to a completely closed metal shield and capacitors. Interference in the lower frequency range can be reliably attenuated with additional capacitors and chokes on the PCB. Especially the interferences in the low-frequency range < 10 MHz are mainly conducted through the cables, which means that the filter components do not necessarily have to be located at the mains input and can simply be placed on the printed circuit board. SCHURTER offers a wide range of current-compensated and linear chokes for this purpose. Typical applications are medical, laboratory, audio and video equipment and industrial systems.

Multiple mounting versions

The new filter series is available in three mounting versions: Screw mounting from the front side with plastic flange, screw mounting from the front or rear side with metal flange and snap-in mounting from the front side. All variants guarantee optimal electrical contact of the mounting panel thanks to the wide metal flange. The closed filter housing acts as optimal shielding of the mains input.

Approvals

The 5121 series is certified for currents up to 10 A/250 VAC according to IEC and 15 A according to UL/CSA at 125/250 VAC. It has ENEC, CQC and cURus approvals.
